Application filed August 26, 1908. Serial No. 450,291.

Toall whom it may concern:

Be it known that I, WILLIAM D. BRECK- ENRIDGE, a citizen of the United States of America, residing atWaco, in the county of McLennan and State of Texas, have in- 1 which it appertains to make and use the same.

This invention relates to oil burners of the type in which crude oil is fed through the burner and commingled at the-tip with 1 compressed air or steam so as to be vapo-' rized and ignited.

The invention consists in certain novel features hereinafter first fully described and then particularly pointed out in the claim.

In the drawings, Figure 1 is a longitudinal section of the improved burner, the internal plug being shown in elevation in order to disclose the air-conveying spiral grooves. Fig. 2 is a similar view with the plug in section.

In carrying out the present invention, I employ a base or block, 1, having threaded openings, 2, 3,'for the reception of the oil and air supply pipes, respectively. From these openings, ports or passages, 4, 5, lead through the block to the end of the same, the oil port, 4, being carried obliquely through the block to the center, of the same. Asingle turning plug valve, 6, controls the two ports so that a single motion will turn on or out off both the air and oil supply. This feature 1 of the invention is very advantageous as the burner maybe used in ordinary cook stoves and by unskilled persons without fearof acbody is reduced to present an annular shoulder,'7, and beyond said shoulder it is threaded as clearly shown; The threaded portion is engaged by a tubular shell, 8,and

4 T the shoulder 7 acts as a stop to limit the sur'ne the oil in wasteful quantities.

One end of thebody, as clearly shown in 1. The shell is formed with interior spiral grooves or threads, 10, and the plug is formed with external spiral grooves, 11, by reason of which the air, steam or other vaporizing.

agent is given a rotary motion as it passes through the burner and emerges from the orifice, 12, with a whirling motion, thereby serving to effectually draw-the oil from the burner and become intimately mixed there with and eifect a complete vaporization thereof. The plug is providedwith a central jet 'opening, "l3 ,in its end whichregisters with the orificein the end of the shell and discharges the oil in small quantities best adapted for thorough vaporlzatlon.

The interior of the plug. presents a rather.-

large bore 14, so that it will register with the oil port 4 notwithstanding slight inaccuratiesof fitting.

The operation of the-burner will be read ly understood. The oil and air ports being open and the burner placed in a stove or other place where heat is desired, the 011 and air will pass through the plug and the space between the same and the shell and commin le at the tip where they will vaporize ant may be ignited. A strong steady flame is produced which may be regulated by anunskilled person and will not con- Having thus described my invention, what I claim. and desire to secure by Letters- Pateut is 2-- The'combination of a body having two inlets, a plug resting against the body and Having an axial bore re 'stering with one specification in the presence of two subscrib-
